let's say Jack holds both balls above
his head and then he drops them at
exactly the same time what do you expect
to see well they're going to hit the
ground at the same time I expect them to
both land at the same time the same time
same
time this one to hit the ground first
however they will actually both hit the
ground at the same time why is that
science yeah science now the black one
clearly feels a lot heavier so the
standard misconception is to believe
that the black ball will accelerate at a
greater rate and reach the ground first
this year many people had an idea that
both balls would land at the same time
but they didn't know exactly why I found
there were some different misconceptions
for example many people seem to think
that as an object falls towards the
Earth it falls with a constant speed
from this hot yeah pretty much just a
constant speed all the way down speed
yeah I think it'll be the same constant
speed I think it's constant I seem to
remember it being constant I did
decently in physics and I se to remember
that's the answer whereas the truth is
the speed of both balls is changing all
the time the balls are speeding up as
they go towards the ground that's what
the force of gravity does on them it
makes them accelerate it gets them to
speed up another misconception I
discovered was that some people believe
both balls should have the same
gravitational force on them even though
the black ball is clearly much much
heavier the reason I think they said
this was because they knew both balls
needed to reach the ground at the same
time so they reasoned that the force on
them must be the same tell me about how
the gravitational force on this ball
compares to the gravitational force on
that ball the force is the same it's
going to be very similar in terms of
gravitational pool they're both have the
same and they'll fall at the same rate
I'm not like Einstein but same
gravitational force around the whole
world right cuz the gravitational pull
on the earth is the same on both objects
are you saying that the force on them is
the same the pull is the same but you
felt the pole and you've told me the
pole is different no I said the weight
is different I didn't say the pole is
different it is heavier and has more
gravitational pull but when I drop them
then they get equal a gravitational pull
somehow don't you think it's going to be
like five times as much yeah you think
but it's not the way you're asking it
yes but scientifically speaking no the
gravitational force on both these fors
are the same okay the gravitational
force on both of these BS is the same is
that what you actually believe no but it
is tell me tell me what you believe I
believe it should be more on this simply
for the fact that this is heavier and
just intuition tells me that should be
more but after learning physics we learn
that it is actually the same I actually
think the force on this ball is more the
force on this I I swear I'm not trying
to mess with
you so like in in real life in real life
and in physics I will tell you that the
force on this ball is more all right
ready three two
one yep see same
time same time same time I would say the
force on the medicine ball is like a lot
more because it's got a lot more weight
it's got a lot more mass but it's got a
lot more inertia yeah yeah oh you guys
remember that right it's got a lot of
resistance to acceleration so it takes
more Force to get it accelerating at the
same rate as this ball and that's why
they accelerate at the same rate thank
you guys so much for playing along I
appreciate that sorry it's all right
